Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation appliances for stroke patients, and specifically to a walking function exerciser for stroke patients to recover walking ability. Background Art

[0002] Stroke, commonly known as apoplexy, is divided into two types: ischemic stroke and hemorrhagic stroke. It is a disease caused by various reasons that damage cerebral blood vessels and cause focal or overall brain tissue damage. The incidence of the disease is higher in cold seasons, and the peak incidence usually occurs in the period approaching noon. Stroke has the characteristics of high incidence, disability rate, recurrence rate and mortality.

[0003] For patients with long-term stroke, their walking ability declines. In hospitals, there are often exercisers to help patients recover. However, when the existing exercisers assist in training at present, most of them bind the patient's legs to the mechanical mechanism to drive the patient to gradually get familiar with the walking posture.

[0004] During this period, the patient's legs are restricted by the fixing objects and have limited movement. Not only is the use experience poor, but excessive assistance is actually not conducive to the recovery of the patient's walking function.

[0005] Therefore, we propose to design a walking function exerciser for stroke patients to recover walking ability. Summary of the Invention

[0025] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0026] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figures 1-5 , the present invention provides a walking function exerciser for stroke patients, including a mounting frame 1. Both sides of the bottom of the mounting frame 1 are fixedly connected with supporting feet 2. One side of the top of the mounting frame 1 is fixedly connected with a first motor 3. The driving shaft of the first motor 3 penetrates through the mounting frame 1 and is fixedly connected with an upper movable arm 4. One side of the outer wall of the upper movable arm 4 is fixedly connected with a second motor 5. The driving shaft of the second motor 5 penetrates through the upper movable arm 4 and is fixedly connected with a lower movable arm 6. Positioning mechanisms 7 are provided at the axial centers of both ends of the upper movable arm 4 and the bottom of the lower movable arm 6.

[0030] The positioning mechanism 7 includes a fixed ring 701, and a movable ring 702 is arranged at the center of the interior of the fixed ring 701.

[0031] Among them, a slideway 8 is opened on the inner wall of the fixed ring 701. A slider 9 is fixedly connected to the back of the movable ring 702. The slider 9 is correspondingly slidably connected with the slideway 8. The slider 9 can move in the slideway 8 to facilitate adapting to the leg movement of external patients.

[0032] A spring 703 is fixedly connected between both sides of the inner wall of the fixed ring 701 and both ends of the movable ring 702. A leg guard 10 is arranged at the center of the inner wall of the movable ring 702.

[0033] Among them, the leg guard 10 is made of silica gel. Its soft texture, good elasticity, and temperature resistance make silica gel more comfortable when contacting the skin and have better skin-friendliness.

[0034] In this embodiment, a combined inlay layer is fixedly embedded inside the leg guard 10. The combined inlay layer includes a vertical plate 101, which is convenient for ensuring the structural strength in the middle of each joint of the leg guard 10. Ring-shaped plates 102 are fixedly connected to both ends of the vertical plate 101. At the same time, at both ends of each joint of the leg guard 10, due to the ring-shaped plates 102 being embedded at intervals, a certain bending range is provided at both ends of each joint of the leg guard 10.

[0035] On both sides of the outer wall of the leg guard 10, a left positioning belt 11 and a right positioning belt 12 are respectively fixedly connected. At the ends of the left positioning belt 11 and the right positioning belt 12, insertion blocks 13 are fixedly connected. Slots 14 are provided at both ends of the movable ring 702. The insertion blocks 13 are correspondingly inserted into the slots 14 and fixed by bolts, which facilitates the docking and installation between the leg guard 10 and the positioning mechanism 7, and is convenient for later replacement and cleaning of the leg guard 10.

[0036] In this embodiment, a nylon hook tape is fixedly connected to the outer wall of the left positioning belt 11, and a nylon fleece tape is fixedly connected to the inner side of the right positioning belt 12. The left positioning belt 11 and the right positioning belt 12 are hooked to each other, which facilitates binding the leg guard 10 to the patient's leg.

[0037] In this embodiment, the three positioning mechanisms 7 respectively correspond to the root of the thigh, the knee joint and the ankle position. First motors 3 and second motors 5 are respectively provided outside two of the positioning mechanisms 7, which facilitates driving the joints and assisting the patient's thigh and the lower leg below the knee to rotate and bend.

[0038] In this device, the mounting frame 1 can be used alone for exercising the single leg for assisted bending. When two mounting frames 1 are used in combination, the patient's walking ability can be exercised.

[0039] When the double mounting frames 1 are used in combination, the patient puts the leg into the opening on the side of the leg guard 10, and hooks the left positioning belt 11 and the right positioning belt 12 at the thigh, knee joint and ankle joint positions through the nylon fasteners in sequence, so that the patient's leg is fixed in the leg guard 10.

[0040] At this time, the root of the patient's thigh, the knee joint and the ankle joint can all move. When moving, the movable ring 702 is driven to move, and the corresponding slider 9 slides in the slideway 8. During this movement, the springs 703 at both ends of the movable ring 702 are compressed, which facilitates providing resistance for the movement of the patient's leg and plays a role in exercising the patient's leg strength. At this time, the activity area is within the range of the fixed ring 701, and the activity range is relatively small.

[0041] Compared with the existing patient walking ability exercise mechanism, when the patient exercises walking with the assistance of a fixed object, the patient's leg cannot move due to being fixed. This device can make the patient's leg more relaxed and free, and the leg strength can be gradually exercised, and the use feeling is more comfortable and better.

[0042] During exercise, it is assisted by an external motor drive. By starting the first motor 3, the upper movable arm 4 can be driven to rotate, driving the patient's thigh to rotate, and then driving the whole leg of the patient to rotate. The first motor 3 in the other mounting frame 1 rotates in the opposite direction, driving the other thigh to rotate.

[0043] Meanwhile, the lower movable arm 6 can be driven to rotate by the second motor 5, driving the lower leg below the patient's knee joint to rotate, so as to simulate the walking posture of the patient, with the legs bent and one foot in front of the other. Repeating this process in sequence, the two legs are driven to adjust one after the other, gradually enabling the patient to become familiar with the walking posture and then gradually restoring the walking ability.

[0044] In this device, both the first motor 3 and the second motor 5 are servo motors, and the drive shafts can rotate forward and backward and lock. At the same time, the coordinated operation between the first motor 3 and the second motor 5, as well as the stroke of the drive shafts of the first motor 3 and the second motor 5, can be achieved through external PLC programming, which is prior art and will not be elaborated here one by one.

[0045] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in the present invention can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
